LATE non wALL-rmsrnn FOUNDATIONS.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed April 23, 1917. Serial No. 163m.

a citizen of the United States, residing at Frankfort, in the county of Franklin and State of Kentucky, have invented certain new and useful Improvements in Wood Laths for Wall-Plaster Foundations, of which the following is a specification.

My invention relates to a wall covering for plaster providing a key base of such self-spaced uniform width as to receive and hold the plaster covering and to give a secure wall in the most economical way possible.

In the drawings accompanying this specification Figure 1 is a front elevation of wall in which my lath is used.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a view of a lath itself.

' Fig. 4 is a vertical transverse section through the wall shown in Fig. 1.

Fig. 1 is a front elevation of wall in which my'lath is used, in which I show studding 5, self-spacing lath 6, intersected by and assembled with plain uncut lath 7 partly covered with plaster 8 and illustratmg the binding tape 9 glued to back of members.

Fig. 2 is a rear elevation of the same showing in addition to above, plaster 1O appearing through "key spaces occupying about of length of lath together with a better view of tape or connecting material 9.

Fig. 3 is a view of a lath itself as it comes from the mill, made of waste lumber of like dimensions of common lath, usually of inch thick .by 1%; in. wideby 48 in. long, having saw cuts in its two edges of proper dimensions to form the key base, each cut diagonally opposite the other so that no two spaces fall directly opposite on same lath. I

Fig. 4: is a vertical transverse section through the wall shown in Fig. 1.

To describe the economy self-spacing lath in detail: It consists of a common wood lath with saw cuts in its two edges in dimensions about 3; in. deep by 1% in. longdiagonally opposite each other so as to form a key base for plaster when assembled alternately with plain uncut lath of like dimensions as shown in Figs. 1 and 2 accompanying this specification.

The economy self-spacing lath follows: 3

First, to provide a simple economical device to overcome the slow, laborious and tedious {process of tacking common wood laths singly on walls and ceilings properly spaced for plastering.

Second, to provide a device that will insure uniform spacing of wood laths automatically in order to procure a key base that will insure a perfectly fastened plaster in the most economical way possible.

Third, to reduce the unnecessary key base area to its real necessity, thereby saving two out of three pounds of plaster required to fill in common wood lath spaces and six to eight pounds out of every 10 pounds so required or some expensive modern devices.

Fourth, a further object is to enable'one to place in position and tack more than one lath. at a time on to the frame work of a building by fastening them together into sections or units of the desired number of self-spacing laths assembled with plain uncut laths as indicated in Figs. 1 and 2.

Fifth, to enable unskilled labor or the plasterer himself in the absence of lather to prepare a wall for plaster in the most economical way ossible.

Having thus i lly described my said invention, the economy self-spacing lath, what I claim as new and desire to secure by Letters Patent is:

1. An article of manufacture, comprising serves as a lath of ordinary standard dimensions having alternately in its opposite edges shallow recesses substantially the size of the cross section of the lath and spaced apart substantially twice their length.

2. A lathing section consisting of a series of laths as set forth in claim 1, each in juxtaposition to and alternatin with one of a seriesof uncut laths, all 0 said laths being glued to and flexibly united by strips of tape so that said sections are capable of being rolled and. unrolled.
